2 Claims. (Cl. 101-3) UNITED STATES PATENT orFicE This'invention relates to hand-operated, mechanically-supported marking devices particularly designed for use in impressing insignia on plastic sheets such as the upper crust for pies. The construction is adaptable for making an impression on dough discs vas the discs pass from a dough roller of a pie machine along an inclined conveyor or slide. 'Ihese discs at the time of receiving the impression may be at different positions on the inclined support either laterallyor longitudinally thereof, and hence it is desirable to provide a mounting for the marker permitting more-or-less universal movement of the marker.

Accordingly it is amongthe purposes of the invention to provide a marking device suitable for the particular conditions mentioned. It is also an object of the invention to provide an improved resilient and adjustable mounting for the marker tending to hold it in some normal clearof-the-work position in connection with an arrangement whereby the marker may be swung entirely out of the way when not in use. i

'I'he objects of the invention are accomplished by a construction as illustrated in the drawing, wherein: l

Figure 1 shows a perspective View of the marking device and indicates broken away an inclined guide chute for articles operated upon.

\ Fig. 2 shows the marker in longitudinal section.

Fig. 3 shows a sectional detail taken on the line 3-3 of Fig. 2. y

Fig. 4 is a sectional detail taken on line 4 4 of Fig. 2. a

Ihe essential elements of the marking device include a supporting base bracket. This bracket is made extensible and includes an upright hollow post within which is slidably supported a post extension element movable with a spring carrier.

The marker is carried at the outer end of telescoping elements suspended by a spring from the carrier and pivotally connected with the post eX- v tension. By this arrangement the necessary freedom of motion of the marker is provided against resilient reaction which tends to hold the marker normally clear of the work.

As shown in Figs. 1 and 2, the extensible bracket base consists of two parts I and 2 which are connected together at the location oi slot 3 in part I by means of the wing nut 4` engaging the threaded stud 6 carried by part 2. The part 2 of the bracket also has a screw clamp 6 for engagement with a supporting flange on a dough rolling or pie making machine. The bracket element I has welded or brazed thereto a vertical tube I forming a hollow post in which is adjustably mounted a tubular element 8 at the top of which is a jointed construction 9 for carrying telescop-ing tubular arms II! and II. A marking head I2 is pinned at I3 to the outer end of tube II. The marking head is arranged to support against rotation detachable type-carrying membersy I4, and also carries an` operating handle IS. Tube il is slotted at I6 to receive the head of a screw Il carried by tube I0. The slot I 5 is wider than the screw in order to allow for a limited rotary motion of tube i I on tube I0. The head of screw Il is connected by a spring I8 with a bent rod I9. The lower end of rod I9 is threaded for the purpose of adjustably engaging a collar 2i! surrounding post l and may be clamped to this collar by the lock nut ZI. The lock nut serves to prevent the rod from rotating in its support. l

Collar and the extension 8 of post 'i are connected together by a screw 22 passing through a vertical slot 23,` Fig. 1, in tube l. By means of this screw the telescoping members l and 8 may be clamped together in the desired adjusted position for determining the normal height of the marker above the inclined chute 2li, Fig. l, for the work. A dough disc is indicated at 25 on the chute.

The joint 9 is a hinge, one member 2d of which is pinned to tube Ill. The other member 25 has an annular groove 26 in which loosely ts a screw 2 carried by post extension 8 for the purpose of allowing free rotation but retention of member 25 within the extension 8.

A moved position of the device is indicated by broken lines in Figure l which serve to show the telescoping members ID and Ii extended and the type carrier turned.

In operating the device, impressions are made through use of the handle I6, whereby the typecarrying tube II is slid outwardly and turned while both tubes are swung downwardly from the hinge to make the impression.

I claim:

l. A marking deviceoi the nature specified comprising a bracket carrying an extensible telescoping post construction, clamping means for the telescoping members of the post, saidclamping means having mounted thereon a spring carrier, a swivel hinge mounted at the top of said. post and carrying apair of telescoping members capable of relative axial motion, a stamping de- 2y f 2,192,417 t,

member, means providing for a limited rotary' 2; A marking device of the nature specied comprising a supporting base and a post supported on said base, a swivel hinge mounted at the top of said post and carrying a pair of telescoping members mounted for a relative axial movement, a stamping device carried by one of said telescoping members to move therewith in an axial direction relative to the other telescoping swivel hinge.
